(Supplement Table 5) Revised chronology of the A/C ratio record from Sumxi Co

Revised chronology of the A/C ratio record from Sumxi Co (Van Campo and Gasse, 1993) based on the digitised A/C ratio values and radiocarbon dates (14C BP) from Van Campo and Gasse (1993) and Van Campo et al. (1996) which were calibrated with CalPal-2007 online using the CalPal-2007-Hulu calibration curve (Weninger and Jöris, 2008; Weninger et al., 2013). For the radiocarbon dates given in Van Campo et al. (1996) we assigned a universal uncertainty range of 100 years.本研究对森西错（Sumxi Co）的A/C比值（A/C ratio）记录的年代序列进行了修订，该原始年代序列源自Van Campo与Gasse（1993）。本次修订基于Van Campo与Gasse（1993）、Van Campo等（1996）公开的数字化A/C比值数据与放射性碳测年数据（14C BP），并采用CalPal-2007-Hulu校准曲线（Weninger与Jöris, 2008；Weninger等, 2013），通过CalPal-2007在线平台完成测年校准。针对Van Campo等（1996）中的放射性碳测年数据，我们统一设定了100年的不确定度范围。
